With Frank's blessing, I have seven of his version 1 (25x100mm) PCBs available. $40 each includes USPS shipping in the US. These are fully assembled and the pots are pre-trimmed, so they will drop into place and work right out of the box. Email me (PMs kill kittens) if you'd like one.

 

The link should work just fine but my provider is not the best. I have a plenty of boards, but only unassembled. A kit is 25 euro inside the EU.
Savington has a couple of my (V1?) assembled kits. Not sure what he's asking for them.

 

hah, you beat me to it

 

thanks again!! this fixed my issue!

 

Hi Frank,

The board being unassembled isn't a problem.

When you have the time please send me a pm with the details.

thanks everyone

 

It warms the cockles of my heart to see my creation increase happiness in the world just a tiny bit.

 

<p>Necro bump for help.&nbsp;</p><p>I'm assembling a v1 board right now. And just tested it. Adjusting the pot lets me change the switchover up to like 13.8 volts. and then as soon as I adjust it anymore, it won't switchover at all.</p><p>I'll try and post a video.</p>

 

<p>Update.</p><p>Here is where I'm at.</p><p>I turn the voltage up to 14.5. Field voltage stays ~14. Turn off the power supply, field voltage is at 0. Turn down the voltage to 14.4 or 3 and the field voltage goes back up.</p><p>Its like it isn't switching correctly.</p>

 

<p>Playing with it some more, I can get it to trigger at 16.5 to zero, then around 13.2 turns it back on. I can't get it any tighter than that.</p>

 

<p>So basically I can't shrink the on/off range small enough. I can only get it to about 13.2-16.8</p>

 

Should be field is 12+ when input is under 14.4v. Over 14.4v and field should be 0.

 

<p>Yeah thats not happening. I can get it so that happens at like 13.6, but then if I adjust the 100k pot anymore it goes wonky.</p>

 

<p>Update.</p><p>If I slowly change the input voltage then I have to go all the way up to ~17 volts for field to drop to zero.</p><p>If I raise it quickly straight to ~14.7 or so then it drops to zero.</p><p>When I slowly raise it to ~16 field reads 14.8.</p>

 

<p>Person who assembled half of the board before me put in a 22ohm resistor in place of a 22k.</p><p>Now to search through all my **** for a 22kohm resistor.</p>

 

Is anyone still selling these?

 

savington still has a few.

 

Awesome! Thanks! Email sent.

 

I'm still selling these as well. I have assembled now as well. Slightly more expensive as Sav's as these are the V2 version.

 

Ok, I have the circuit from Savington. I have a question... I am hooking this to a DIYPNP MS2 for a 99-00. The 12+ Wire goes to a 12 volt pin on the ECU and ground to ground. I Think the Field wire goes to pin 1o. Where does the Disable wire go?

 

<p>Probably nowhere.</p><p>You can hook it up to an output on the ms to turn the the alternator off. Not sure if you have enough spare outputs though.</p>
